Ron very quickly diagnosed what was wrong with my GivEnergy system. Unfortunately the kit has died after only 3.5 years of use-which is quite sad and timing couldn’t be worse with GivEnergy gone bust. Ron gave me advise on how to handle this with my installer. I’m hoping they’ll be forthcoming, but if they aren’t i now have a good idea how to deal with that. Thanks a lot Ron!
Particularly useful in helping to fix my GivEnergy All in One system with a disabling fault.
After recently changing my fuse board the ct clamp broke, this meant my inverter was not communicating properly with my GivEnergy system. After several people letting me down, finally got put in touch with Ron. He came out within 24hours & resolved the fault within an hour, no fuse just got on with it. Work was tidy & arrived when he said he would. Ron followed up a few days later to confirm all was still good, great service from all involved.
Absolutely wonderful support. I have a GivEnergy system that was installed in 2022, and a firmware update was flagged in the app, so I proceeded to update the software .... and immediately regretted it, as my inverter came up with an error, and was not working at all! With no GivEnergy support available, and my installer saying there was nothing he could do, I googled help, and found Ron. What a stroke of good luck! Submitted an on line enquiry late morning, and received phone call just after 5 pm, and later that evening Ron was able to supply me with old firmware no longer available on the GivEnergy web site. I was then able to update the firmware using a GivEnergy youtube video as reference, and hey presto the system was back up and running. One further slight adjustment by Ron and we are back normal. What a relief. I have no hesitation in recommending Solar Tech Support if you have a problem. Great service! And if you are a GivEnergy system owner, whatever you do, DO NOT UPDATE FIRMWARE!
Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.
Roland is a true gentleman. He provided a refurbished inverter when my givenergy one failed. The install was a pain and took him hours. I was expecting a big bill but he honoured his price despite the extra effort. While here he diagnosed a battery fault. He helped me get the battery down and recommended an excellent company who could repair the battery. Absolute legend of a person and company
These three checks resolve the majority of apparent hardware faults without any tools or specialist knowledge. Do them first. The first one uses the GivEnergy portal at givenergy.cloud, which is part of GivEnergy Premium; without Premium, use the GivEnergy app on your home network. The portal and app are run by GivEnergy Software Ltd (Companies House 14899764), which is still trading. It is a separate company from GivEnergy Ltd, which has been in administration since 9 April 2026. Companies House showed a proposal to strike GivEnergy Software Ltd off from 15 September 2026, suspended on 30 September 2026, and its parent company changed to IEMCS Limited from 11 August 2026 (checked 24 October 2026). What the administration does and does not affect.
Log into givenergy.cloud → My Inverter → Remote Control → Battery. Look at the Pause Battery setting. If it shows Paused, the battery is deliberately halted — it will not charge or discharge regardless of schedule, mode, or any other settings. This setting is the most overlooked cause of apparent hardware faults. Set it to Not paused if incorrectly set.
Physically inspect every isolator switch in the system. On GivEnergy systems, handle pointing UP means ON. A horizontal or downward-pointing handle means the circuit is open. An accidental knock or a deliberate service switch-off that wasn't reversed can leave an isolator in the OFF position and take down the whole system.
Look at the LED indicator on the GivEnergy inverter. A solid green LED indicates normal operation, and flashing green means waiting mode, which is also normal. Any other colour needs checking: note the colour, then check the event log and the GivEnergy fault code guide for the meaning before proceeding further.
GivEnergy systems have multiple isolator switches. All must be in the correct position for the system to operate. The rule is simple: handle UP = ON.
The AC isolator controls the mains electricity supply to the inverter. It is typically located near the consumer unit or inverter mounting position. Handle pointing UP = ON (closed). If this is OFF, the inverter has no mains supply and will not operate.
The DC isolator isolates the solar panel strings from the inverter. On most GivEnergy installations it is located near the inverter. If the DC isolator is OFF, the inverter cannot receive solar power. Handle UP = ON.
The battery isolator is the battery's DC MCB. Where it is depends on the battery, not the inverter. Gen 2 and Gen 3 batteries (9.5 kWh and 5.12 kWh) have it built in, behind the battery flap. Gen 1 batteries (2.6, 5.2 and 8.2 kWh) use a separate DC breaker fitted in the cable between the inverter and the battery. If it is OFF or has tripped, no power flows between the battery and the inverter, so there is no charging or discharging. The comms stay connected, so the system can still see the battery and its lights may look normal. Confirm the handle is pointing UP (ON).
The status lights give a quick indication of system state. Solid green is the target, and flashing green on the inverter (waiting mode) is also normal. There are no flash patterns that mean different faults: note the colour, then check the event log.
| Light | Meaning | Action |
|---|---|---|
| Solid green (inverter or battery) | Normal operating state | No action needed |
| Flashing green (inverter) | Waiting mode, which is normal | No action needed |
| Solid amber / orange (inverter) | Warning condition | Check portal event log for warning code |
| Amber / yellow (battery) | The BMS is not talking to the inverter. Not a WiFi or portal problem | See BMS Comm Fail |
| Solid red | Fault: needs investigating | Note the colour, check the event log, then see GivEnergy fault codes |
| Flashing red (Gen 1 or Gen 2 battery) | Very low state of charge, not a fault code | Check the event log. If it does not start charging, contact us |
| Red and green flashing together (battery) | Firmware update in progress | Leave it alone. Do not switch anything off |
| No LED / off | No power — inverter not energised | Check AC isolator position |
LED behaviour varies slightly between GivEnergy inverter generations. If the light you are seeing is not in the table above, send us the colour. We will check it against the event log on your system and tell you what it points to. Free remote diagnostic.
GivEnergy batteries have built-in temperature protection that can prevent charging in cold conditions. This is often mistaken for a hardware fault.
GivEnergy lithium batteries will refuse to accept a charge current if the battery cell temperature drops below approximately 0°C. This is a Battery Management System (BMS) protection measure that prevents lithium plating — a form of cell damage caused by charging at very low temperatures. It is not a fault; it is expected protective behaviour.
The battery will automatically resume charging once the temperature rises above the threshold. If you are in a cold snap and the battery is in an unheated garage or outbuilding, this lockout may persist for several hours.
Log into givenergy.cloud → My Inverter → Event Log
Look for any temperature-related events — BMS temperature protection events will appear here when the lockout activates.
Some portal versions show live battery temperature in the monitoring dashboard — check the battery details panel.
If the system is behaving erratically or displaying unexpected errors after configuration changes, resetting the inverter to factory default settings can clear corrupted configurations and restore normal operation.
Log into givenergy.cloud and navigate to My Inverter
Go to Settings (usually in the left menu or main dashboard)
Look for an option labeled Reset settings to default or Factory reset
Click the reset button and confirm. The inverter will reboot with factory settings.
Reset the inverter settings if:
The GivEnergy portal (My Inverter → Software) and the GivEnergy app show your firmware versions and offer updates. The portal and app are run by GivEnergy Software Ltd, which is still trading, not by GivEnergy Ltd, so the update screen is still there. We don't advise running an update from the portal or app. We update GivEnergy firmware manually, to our own written procedures, with the right file for your inverter and battery: on a callout, or by talking you or your electrician through it remotely. If you think your system needs an update, contact us.
An update on offer in the portal or app does not mean your system needs it. Firmware updates can fix known issues, but they are not a fix for hardware or configuration faults, and they can reset your settings. There is no point checking week after week: GivEnergy Ltd made the firmware and has ceased trading, so new releases are not expected. Please do not go hunting for firmware files elsewhere. Unofficial .bin files are a good way to brick an inverter. If your system genuinely needs a particular firmware version, we hold the GivEnergy firmware. We can apply it on a callout, with the price agreed before any work starts, or supply the right file and talk you or your electrician through it remotely. Ask us about firmware. The settings an update can reset, and what to do if one stalls, are on our firmware update page.
GivEnergy's own guidance is not to update firmware while the battery is in a fault state, is not charging or discharging properly, or shows 0%: an update during a fault can leave the firmware stuck and make recovery harder. Nobody should start an update unless all of these are true:
The battery percentage must be showing in the portal. If SOC is not displayed, there may be a communication issue that should be resolved first.
The battery must show active charge/discharge current during the update. A standby battery may lose communication mid-update.
The battery module must show a steady green LED. Any other colour, or a flashing light, means there is a problem to resolve first.
The inverter LED must be green, and the portal must show no active faults or alarms. All error conditions should be cleared before updating.
Do not power off the system during the update. The inverter may restart and reinitialise several times, which is normal, and red and green lights flashing together on the battery mean the update is in progress. GivEnergy's firmware update guide gives 5 to 30 minutes for an update from the portal.
Once the update finishes, the inverter will restart automatically and return to normal operation. The portal will confirm the new firmware version once the update is complete. If it still shows Updating after an hour, follow the one-hour rule.
A controlled restart can clear transient faults and restore normal operation. The order matters: the wrong order can create new fault conditions on startup.
The one rule to remember: the battery goes off first and the DC MCB last, then the AC comes back on first. Shutting the inverter down while the battery is still live can latch a BMS protection state. The full steps live on our GivEnergy restart guide.
No isolators to touch, and your settings are not affected. See the battery-only restart for a Hybrid or an AIO.
Follow the full sequence for a Hybrid (separate inverter and battery) or an All-in-One. The waits matter: a restart started too soon can bring the same fault straight back.
If the LED is still not green after a full restart, if the system shows a persistent fault code you can't identify, if a battery module is not communicating (BMS Comm Fail), or if there are signs of physical damage — stop and contact us. Repeated restarts on a faulted system can cause further damage. We can review portal data and event logs remotely before recommending a site visit.
